PST vs Thousand Oaks Optical dilemna

I am facing a dilemna! I would like to start observing sun prominences and I have two options:
- Purchase the H-Alpha prominence filter from Thousand Oaks Optical to fit my 8" SCT ($839)
- Purchase a PST ($500)
The price range is "comparable" so it really is all about the end result and viewing satisfaction.
Any thought?
Thank you.

If all you want to observe are prominences then the thousand oaks filter will work for you because that's absolutely all it will show you. On the other hand, the PST will show you prominences plus a rather good amount of surface detail (filaments, etc.). It wouldn't be a hard decision to make for me, the PST shows more and cost less, the only draw back for me is that the PST is not binoviewer friendly...yet. For less money than the thousand oaks filter you could buy the PST, a white light filter for your SCT and a mounting rail to mount the PST on top of the SCT.

I have a PST mounted on an Orion AZ3 mount and it absolutely blows me away every time I take it outside.

The only problem I have is now I want more. The binoviewer, prime focus CCD imaging, Ca-K swappable filter, built-in chair and more clear days.
